Patent JP-S6276565-A (JP)
Title: Field-effect type transistor
Inventor: HIKOSAKA YASUMI
IPC: H01L29/778
Filed: 1985-09-28
Abstract: PURPOSE:To reduce a threshold variation to a temperature by forming one thin barrier, to which carriers can be turned, into a single quantum well and doping an impurity only into a region having narrower width in two or more of well regions partitioned by the barrier. CONSTITUTION:Each layer of respectively non-doped i-AlGaAs layer 2, a single quantum well (SQW), i-AlGaAs 8 and i-GaAs 9 is shaped onto a semi-insulating (Si)GaAs substrate 1. The mol ratio (x) of Al in the i-AlGaAs layers 2, 8 extends over 0.2-1.0, and it is brought to 0.2-0.3 in this case. The single quantum well (SQW) layer is constituted of i-GaAs 3, an i-AlGaAs barrier layer 4, i-GaAs layers 5, 7 and a doping layer 6, and the doping layer is formed in a planar-doping or high doping manner. A diffusion to the i-GaAlAs layers 8, 4 of a dopant by a diffusion is prevented because the non-doped i-GaAs layers 5, 7 are shaped on both sides of the n-GaAs 4 in the doping layer.
